2.37. A cranked shaft
THE GENERAL DATA

Check of a lateral backlash of a rod

AND. MEASUREMENT OF THE LATERAL BACKLASH OF THE ROD


To remove or disconnect

PERFORMANCE ORDER
1. The engine.
2. To merge oil.
3. To establish the Engine on the stand.
4. To unscrew spark plugs 20.
5. A pulley 145 with a nave.
6. A cover of a gear belt.
7. A gear belt 44, having weakened bolts of fastening of the water pump.
8. A flywheel 116.
9. The oil pallet 125.
10. A cogwheel 141 cranked shaft.
11. A back cover of a gear belt.
12. The oil pump 137.
13. Covers of 157 rods with loose leaves, preliminary having marked.
14. To remove pistons 160 with rods 159 from necks of a cranked shaft.
15. Covers of 122 radical bearings with loose leaves 120 and 121. Preliminary to mark details.
16. A cranked shaft.

To clear

PERFORMANCE ORDER
1. Oil, a dirt and a deposit.
2. Oil channels from stoppers and adjournment.

To check up

PERFORMANCE ORDER
1. A shponochnuju flute.
2. A carving.
3. Necks of bearings and persistent fillets on presence:
      – Cracks;
      – выкрашивания metal;
      – Deepenings;
      – Roughnesses;
      – Flutes;
      – Overheat traces.
The prevention

To examine corresponding loose leaves on presence of impregnations of extraneous particles, in the presence of similar defects it is necessary to find out an origin of these alien particles.

In the presence of cracks or other deep defects of workers поверхнос тей it is necessary to replace a cranked shaft. Small roughnesses can be smoothed down the thin skin moistened in engine oil. Teases delete by means of thin grinding бруска.


To measure

PERFORMANCE ORDER
Necks of a cranked shaft. To measure deviations from цилиндричности (конусность) and круглости (ovality) by means of the indicator or a micrometer. If the sizes and the form of necks are in admissible limits, it is necessary to write down results of measurements for the subsequent selection of the complete set of loose leaves. If unsatisfactory, it is possible to restore a condition of necks рабоспособность a shaft repolishing of necks. Shaft with накатанными галтелями are subject to replacement.
The prevention

To check up an arrangement of ledges of the radical bearing. If they are located not in a line, a cranked shaft will drive, and is subject to replacement.


To establish or attach

PERFORMANCE ORDER
1. New loose leaves 120,121, a cranked shaft 119.
2. Covers of 122 radical bearings with new loose leaves. Not to tighten bolts 123. Preliminary to oil loose leaves.
3. To establish heads of rods with new loose leaves 158 on necks of a cranked shaft.
4. Covers of rods with new loose leaves. Not to tighten шатунные bolts 156. Preliminary to oil loose leaves.
5. Blows of a hammer with rubber brisk on the ends of a cranked shaft to centre persistent bearings 121.
6. To tighten bolts of radical bearings the moment of 50 Nanometers., then in addition to tighten their turn on a corner 45 –60 . To check up an axial backlash of a cranked shaft. It should be within 0,07–0,30 mm.
7. To tighten bolts шатунных bearings the moment of 25 Nanometers., then in addition to tighten their turn on a corner 30 .
8. To measure lateral backlashes of all rods. Backlashes should be within 0,07–0,242 mm.

12. A cogwheel 141.
13. The oil pallet 125.
14. New back consolidation 117.
15. A flywheel to tighten bolts the moment of 35 Nanometers, then in addition to tighten turn on 30 –45 .
16. A gear belt and a cover.
17. A pulley to tighten bolts the moment of 55 Nanometers.
18. Spark plugs.
19. To establish the Engine on the car.
20. To fill in engine oil.
